What I'm looking for

I seek SAP BASIS roles focused on S/4HANA migrations, HANA administration, and ECS architecture in collaborative teams that value reliability, automation, and mentorship.

I am an SAP BASIS Consultant with 3.7 years of hands-on experience administering NetWeaver and non-NetWeaver landscapes across cloud and on-prem environments. I specialize in ECS architecture, S/4HANA upgrades, HANA and Sybase administration, system copy using SWPM, and zero-downtime migrations.

At Tata Consultancy Services I independently supported 20+ SAP systems (ECC, S/4HANA, PI, BW) for 1,500+ users, executed an S/4HANA 1909→2021 upgrade using SUM with zero downtime, and delivered a homogeneous system copy with automated post-migration checks that reduced validation time by 30%.

I emphasize reliability and knowledge sharing: I resolve 40–50 incidents monthly with 98% SLA adherence, document operational processes, participate in code and change reviews, and mentor junior consultants to build SME capability.
